Simple Metal Detector Circuit Diagram using 555 Timer IC
https://circuitdigest.com/electronic-circuits/simple-metal-detector-circuit
Metal Detector Circuit Diagram and Working. The figure shows the circuit diagram of metal detector . The 555 IC timer here acts as a square wave generator and it generate pulses with frequencies audible to human. The capacitor between pin2 and pin1 should not be changed as it is need to generate audible frequencies.

These metal detector circuits are being used in plenty of places. Most of the security officers use it to detect metal devices like guns, knives, etc. A metal detector is a circuit that senses any metallic object close-by. These metal objects are very useful to detect the presence of any hidden object. A simple metal detector uses a 555 Timer IC. The Metal …
Metal Detector using a 2 Pulse Induction Coil
http://users.cecs.anu.edu.au/~Salman.Durrani/_teaching/TA5.pdf
connected to an audio circuit, where it is changed into a tone that the metal detector uses to indicate that a target object has been found. PI-based detectors are not very good at discrimination because the reflected pulse length of various metals is not easily separated. However, they are useful in many
Simple Metal Detector using CA3140 IC - Circuits DIY
https://circuits-diy.com/simple-metal-detector-using-ca3140-ic/
This circuit is working on the basis of a BiMOS operational amplifier IC CA3140 and can be operated at 9-12V. A coil is used to sense the presence of any metal around the circuit. After detecting a metal it sends an input signal to the op-amp IC. A 2N3904 transistor is connected at the output of this IC to drive the piezo buzzer and the Led.

Sensitive Audio Detector | AC Circuits | Electronics Textbook
https://www.allaboutcircuits.com/textbook/experiments/chpt-4/sensitive-audio-detector/
Solder all wire connections well. This detector system is extremely sensitive, and any loose wire connections in the circuit will add unwanted noise to the sounds produced by the measured voltage signal. The two diodes connected in parallel with the transformer’s primary winding, along with the series-connected 1 kΩ resistor, work together to “clip” the input voltage to a maximum …
